Hot tubs and spas in Hendersonville require a permit from Building & Codes (615-822-3802) under the City-adopted 2021 ISPSC and 2020 NEC. ISPSC barrier requirements (Section 305) apply, but Section 305.5 provides an important exception: a spa or hot tub equipped with a safety cover that complies with ASTM F 1346 is exempt from the 48-inch barrier provisions. Hot tubs also require dedicated 240V GFCI-protected electrical service per NEC Article 680.42, with shut-off disconnects within sight and at least 5 feet from the tub.
Spas and hot tubs are classified by the 2021 ISPSC as 'swimming pools, spas, and hot tubs' under the Section 202 definitions and are subject to the same Chapter 3 general compliance and Section 305 barrier requirements as in-ground pools, with one critical exception. ISPSC 305.5 (Indoor and outdoor spa or hot tub) states: 'A spa or hot tub equipped with a safety cover that complies with ASTM F 1346 shall be exempt from the provisions of this section.' This means a hot tub with a listed locking safety cover meeting ASTM F 1346 (Standard Performance Specification for Safety Covers for Swimming Pools, Spas and Hot Tubs) does not have to have a perimeter barrier or self-latching gate, as long as the cover is in place when the spa is not in use. Electrically, NEC Article 680 Part IV (680.40-680.43) requires hot tubs and spas to be supplied by a dedicated branch circuit with GFCI protection (680.43(A)), a clearly labeled disconnect within sight of the spa but at least 5 feet from the inside walls (680.42(C)/680.13), equipotential bonding of all metal surfaces within 3 feet of the tub, and listed packaged equipment that complies with UL 1563. The City of Hendersonville Building & Codes Department reviews hot tub permits with the same Swimming Pool Plan Submittal Checklist required for pools, including 'Pool fencing design and location to show enclosure around pool area' and 'All gates to indicate swing away from pool' (where a barrier is used instead of an ASTM F 1346 cover). Hot tubs placed on a deck or accessory structure must be supported by a structure designed for the live load (roughly 100 pounds per square foot for water plus occupants). Outdoor hot tubs must comply with the Hendersonville Zoning Ordinance accessory-use setbacks (Chapter 10.4) - generally rear or side of the home, behind the front facade, and respecting the 5-foot or 8/10-foot side setbacks applicable to accessory structures in SR-1/SR-2 districts (10 feet SR-1, 8 feet SR-2 from side lines; 20 feet from rear; with a 5-foot exception for accessory structures not over 400 square feet at least 10 feet from the house). Lakefront properties must also respect TVA shoreline easements.
Installing a hot tub without a permit violates the City-adopted 2021 ISPSC and may result in a stop-use order from Building & Codes. Missing or non-compliant ASTM F 1346 cover (when used to satisfy the barrier exception), no GFCI on the spa circuit, disconnect not within sight or too close to the spa, missing equipotential bonding, or accessory-use setback violations in SR-1/SR-2 are all enforceable. Hot tubs that drain into the City sanitary or storm system without authorization can additionally violate Title 18 (Water and Sewer).
